NAME

sane-cardscan - SANE backend for Corex CardScan 800c usb scanner

DESCRIPTION

The sane-cardscan library implements a SANE (Scanner Access Now Easy)
backend which provides access to the Corex CardScan 800c small-format
scanner.
The backend supports only grayscale and color modes and media of
(theoretically) infinite length.
This backend may support other scanners. The best way to determine
level of support is to get a trace of the windows driver in action, and
send it to the author.

OPTIONS

The cardscan backend supports the following options:
mode m
Selects the mode for the scan. Options are "Gray" and "Color".

CONFIGURATIONFILE

The configuration file "cardscan.conf" is used to tell the backend how
to look for scanners, and provide options controlling the operation of
the backend. This file is read each time the frontend asks the backend
for a list of scanners, generally only when the frontend starts. If the
configuration file is missing, the backend will use a set of compiled
defaults, which are identical to the default configuration file shipped
with SANE.
Scanners can be specified in the configuration file in 2 ways:
"usb 0x04c5 0x1042" (or other vendor/product ids)
Requests backend to search all usb busses in the system for a
device which uses that vendor and product id. The device will
then be queried to determine if it is a cardscan scanner.
"usb /dev/usb/scanner0" (or other device file)
Some systems use a kernel driver to access usb scanners. This
method is untested.

KNOWNISSUES

The scanner does not seem to have much control possible, so the
backend cannot set x/y coordinate values, resolutions, etc.
These things could be simulated in the backend, but there are
plenty of command line tools.
The backend also does not send all the commands that the windows
driver does, so it may not function the same.
The backend does not have the calibration or ejection options of
the windows driver.
